I flew alone with a 15 month old AND a 3 year old and I have to say it was easier than when I tried to do it with their dad... well, except for when I had to take the 3 year old to the bathroom and the 15 month old screamed from her seat the whole time and I couldn't shut the door to the plane bathroom, so my kid was on the pot, I was trying to keep him from touching anything, with my own backside sticking out the door as I kept trying to pop out and reassure the baby 10 rows back... another mother tried to help... fun times.. but it was only 5 minutes... the rest felt like cake! :) Really!
